its a 5.0 v8 86 oldsmobile cutlass supreme and there is no compression in any cylinder. the firing order is correct, nothing seems to be out of place. the valves are moving and the pistons are moving and it doesn't appear to jump time. when trying to turn over it just whizzes over and won't fire. example would be if you took the spark plugs out of a regular working motor and tried to turn it over. and all the spark plugs work. i am puzzled and don know what could be wrong

Lost of compression...bad compression rings/ bad valves,head gasket, did you use a compression tester, adding oil to the cylinders would let you know if the rings are bad....just a table spoon to each one,...if compression jumps up quickly its the rings and if nothing changes.....valves?
